there's a cat in my blindspot

my father is technically legally blind.  he suffers from retinal pigmentosa which is a degenerative disease which basically means his eyesight will just continue to get worse.  he is also deaf.  thankfully, he does still have a sense of humor.
several months ago my brother, jim, and his wife stopped by my father's apartment. they walked in and saw a black cat walking around like he owned the place.  jim mentioned to our dad that there was a cat in his apartment. dad frantically started rushing around trying to find the cat.  you know, since, he doesn't own a cat.  i'm sure the neighbor was pleased to have their car back.  who knows how long that cat was in there.
